A mower of the character described has a cutter and a casing enclosingthe top and sides of the cutter; and in a power operated mower a motoreither of the internal combustion type, or an electric motor, is mountedon the casing to operate the cutter. However, the bottom of the casingmust be left open to permit the cutter to cut or clip the vegetation,such as grass. The cutter is therefor left exposed and if moved over anobstacle will strike the same. If the obstacle be a foot or hand of theoperator, it may be severely damaged. If the obstacle be a small animal,such as a baby rabbit, the latter will be severely injured and in somecases killed. If the obstacle be something inanimate, such as rock orwood, the cutter will be damaged or dulled and in some cases broken.

While guards have been provided for the bottom of the mower casing, andwhere the guard comprises continuous parallel bars, then accordingly,there will be upstanding grass ridges left below each bar as the mowermoves over the ground.

One of the objects of this invention therefor is to provide a guard of anovel construction operating in an improved manner.

Further objects will appear from the detailed description in connectionwith the accompanying drawing disclosing embodiments of this invention;it is to be understood that this invention is not to be restricted orlimited to the embodiments disclosed and shown, except as defined by theappended claims.

In the drawing:

Fig. 1 is a perspective view of a standard lawn mower of the motordriven type showing the guard attached to the bottom of the casing;

Fig. 2 is an enlarged longitudinal section along the line 2-2, Fig. 1; v

Fig. 3 is a bottom sectional view along the line 3--3, Fig. 2;

Fig. 4 is a perspective view of a guard illustrating one embodiment ofthis invention; and

Fig. 5 is a partial perspective view showing another embodiment of thisinvention.

Generally stated and in accordance with illustrated embodiments of thisinvention, the guard comprises sections of spaced parallelbars arrangedin transverse staggered relation. The guard comprises sections, eachsection having bars arranged in spaced parallel relation, the bars ofthe sections being arranged in transverse staggered relation. Suitablemeans are provided for locating the guard on a mower casing, and meansare provided for attaching the guard to a mower casing.

Referring to the accompanying, Fig. 1 shows generally a lawn mowercomprising a casing 10, provided with wheels 11, and having mountedthereon a motor 12, whose shaft 13 carries a cutter 14 of any suitableconstruction. The cutter is positioned, as shown in Fig. 2, at adistance above the wheels 11, and in some cases 1 Ce v 2,934,882

V 2 v above the bottom of the casing, which distance is usuallyadjustable in any suitable manner. In such a mower, unless provided witha guard, the bottom of the casing is left open.

The guard comprises sections of spaced parallel longbars 20 and 21, thatis' they extend along the direction of movement of the mower. Theselong-bars of the respective sections are arranged in transversestaggered relation. That is accomplished in Figs. 1-4 by attaching thelong-bars 20 and 21 of the respective sections to a cross-bar 22, as bywelding. The outer ends of the longbars are bent upwardly, as shown at23, or are attached to cross-pieces 24 in any suitable manner, as bywelding. The cross-bar 22 has at each end thereof attached theretolocating bars 25 also in transverse staggered relation, which are bentup as shown at 26 hearing against the outside or inside of the casing inorder to locate the guard laterally, while the cross-pieces 24 locatethe guard longitudinally by taking against the ends of the casing. Theends of the cross-bar '22 are provided with spring suspensions 27,having eyes 28 by which the guard may be held on the casing 10 by anysuitable fastener, such as screws 29.

In Fig. 5 the cross-bar 22 of Figs. 1-4 is omitted and the long-bars'200and 210 attached to the cross-bars 240 are connected by bends 31,extending transversely of the guard so that the long-bars 200 and 210are again in transverse staggered relation.

The bends 31 of each of the outer long-bars 200 and 210, only one sideof which is shown in Fig. 5, are connected by pieces 33 to the locatingbars 250 also in transverse staggered relation and having upstandingbends 260. An extension 34 is attached at 35 to the suspension 270having an eye 280. The attachment of the guard of Fig. 5 to the mowercasing can be made as in Fig. 1.

In Figs. 1-4, the guard, which is removable, is located on the bottom ofthe mower casing by the cross-pieces 24 and the locating bars 25 andthen attached by the suspension 27.

-As the mower moves over the ground, the vegetation, such as grass, isdepressed by the forward long-bars 20 and will be cut off by the cutter14. However, as the grass strikes the cross-bar 22, the grass will bepressed down by the forward long-bar 20 and will move into the spacesbetween the rear long-bars 21 and will also be cut off. In this way,small upwardly projecting ridges of grass which have been pressed downby the forward long-bars 20 will be cut 05 after they have passed thecross-bar 22 and go inbetween the rear long-bars 21. In that manner, thecut grass will show an even appearance and will not have the unsightlyridges as usual.

In Fig. 5 the forward long-bars 200 are again in staggered relation withrespect to the rear long-bars 210, and the operation will be the same ashere in Figs. 1-4, because the bends 31 in Fig. 5 act in the same senseusual- 1y as does the cross-bar 22 in Figs. 1-4.

In accordance with this invention therefore, the guard for a mower has asupport and has a cutter at the bottom thereof, the guard having means27-28 adapted for attachment to the bottom of the support and below thecutter. The guard comprises connected sections of spaced long-bars 20and 21 arranged in parallel relation along the longitudinal axis of thesupport, the bars of the respective sections being arranged intransverse staggered relation. The long-bars of the respective sectionsare connected by means 22 and 31 transverse to the longbars.

Having thus described the invention, what is claimed and desired to besecured by Letters Patent is:

l. A guard for a mower hoving a support and having a cutter at thebottom thereof, said guard having means Patented May 3, 1960;
